TECHNOLOGY FOR PRODUCING MINERAL FIBERS BY RECYCLING ASH-SLUDGE AND OIL-SHALE WASTES

摘要

The technology for recycling ash-sludge and oil shale wastes using an electro-plasma facility in the production of mineral fibers, for melting silicate-containing materials, and schemes for additionally heating the silicate melt stream at the exit from the melting furnace is described. Studies of the electro-plasma facility and raw materials as well as the mineral fibers obtained with their use have been performed.
